Visual Corona Inception Voltage Calculator

Estimate the corona inception voltage using Peek's empirical relation.

Formula (for a bare conductor in air):
\[ V_{ci} = 2110\, m_0\, \delta\, r \ln\left(\frac{D}{r}\right) \]
where \(r\) and \(D\) are in meters (converted to cm internally), \(V_{ci}\) is in kilovolts.

* Enter the conductor radius, spacing (both in m), air density factor (δ), and surface condition factor (m₀).

Step 1: Enter Parameters

Conductor Radius, \( r \) (m):

Example: 0.01 m (1 cm)

Conductor Spacing, \( D \) (m):

Example: 0.1 m (10 cm)

Air Density Factor, \( \delta \):

Typically 1 under standard conditions.

Surface Condition Factor, \( m_0 \):

Typically 1 for smooth conductors.
